Definitions

  • the invention relates to a removal tool for propellant charge modules mounted one behind the other and having a free ignition channel.
  • a removal tool for propellant charge modules mounted one behind the other and having a free ignition channel.
  • Such storage of modular propellant charges each having a free ignition channel can be found, for example, in DE 34 37 588 A1 as known.
  • the propellant charge modules are then removed from the magazine and then fed behind the weapon barrel automatically by means of a controllable transfer arm and a charging cradle.
  • care must be taken that the propellant charge modules stored in rows in the magazine can be quickly removed manually and fed to the cargo space of the weapon barrel in the intended propellant charge length.
  • the object of the invention is to provide a removal tool that allows a portioned, quick manual removal and a manual loading process of propellant charge modules that are stored one behind the other and provided with an ignition channel.
  • the invention advantageously enables simple operation of the emergency operation in that propellant charge modules stored in a propellant charge magazine and having a free ignition channel can be manually removed in required portioned propellant charge sets by means of the removal tool according to the invention.
  • the free space of the respective ignition channel of the propellant charge modules is advantageously used for manual removal.
  • a simple actuation of a handle attached to the outer end of the support rod of a clamp device mounted in the support rod ensures that the propellant charge module arrested in the axial direction against the depth stop and can be safely delivered to the cargo area of a barrel weapon by the operating personnel on the handrail.
  • the clamping device generates a clamping force pointing in the direction of the depth stop on the outside of the last received propellant charge module, as a result of which all received propellant charge modules are held securely.
  • the clamping device Because the actuating plunger of the clamping device, which can be operated manually from the outside, is mounted within the holding rod, the clamping device is protected in a space-saving manner, and also to a large extent against external influences.
  • the clamping device provides leaf springs arranged several times on the holding tube, which can be easily spread apart by the actuating plunger at their outer end and clamp the propellant charge module that was last picked up on the outside.
  • Cams arranged on the inside on the leaf springs and, for example, hemispherical, enable a targeted spring spreading by actuating the actuating plunger, which has a larger and rounded cap in the front area, the springs gently adhering to the existing outside transition radius of the ignition channel of the last charged propellant module invest.
  • the actuating plunger is returned in its initial position automatically by means of a compression spring, so that after the clamping process has ended, the leaf springs can also spring back into the provided recesses in the holding rod.
  • the required number of propellant charge modules can be accommodated by simply adjusting the depth stop, with markings on the holding rod indicating the correct length of propellant charge and the depth stop being able to be determined in a form-fitting manner within the turns arranged on the holding rod.
  • the removal tool mainly consists of easily produced, rotationally symmetrical parts that can be easily assembled using screw connections.
  • FIG. 1 shows the removal tool with, for example, five propellant charge modules 17 taken from a propellant charge magazine, not shown, in which the propellant charge modules are mounted one behind the other and have an ignition channel 13 (FIG. 2).
  • the removal tool consists of a holding rod 12 which can be pushed through the ignition channel 13, a depth stop 14 which is axially adjustable on the holding rod 12, a handle 10 which is fixedly connected to the holding rod 12 and a clamping device which is shown in more detail in FIGS. 2 and 3 and which consists of an actuating handle 11 , an actuating plunger 32, a cap 34 and leaf springs 28 with inner cams 26.
  • the depth stop 14 on the holding rod 12 is set to a specific propellant charge length by means of a fastening screw 16, in order to determine the number of modules to be accommodated, the fastening screw 16 via a radially arranged thread 18 of the depth stop 14 in a circular shape provided on the holding rod 12 several times on the outside Twists 20 is held positively axially. So that the axial setting position of the depth stop 14 can be recognized by the personnel there are also additional markings 22 on the circumference of the holding rod 12, at the same distance from one propellant charge module length, which can be designed, for example, as grooves.
  • the clamping device is actuated by manually pressing the actuating handle 11 against the handle 10.
  • the actuating plunger 32 is axially displaced within the support rod 12 and spreads through its contact with preferably semicircular cams located on the inside of the leaf springs 28, which can also have an inclined contact surface in a manner not shown, so far apart that the propellant charge modules 17 received axially be locked against the depth stop 14.
  • the end of the first propellant charge module 17 bears against a radially extending stop face 19 of the depth stop 14, while the last charge propellant charge module 17 is held in the outer rounding of the ignition channel 13 by the leaf springs 28.
  • the actuating plunger 32 of the clamping device is arranged in a longitudinal bore 33 of the holding rod 12 and is fixedly connected to an actuating handle 11 at its end protruding from the handle 10 via a fastening means 46 designed as a securing pin.
  • the actuating plunger 32 contains at its end facing away from the actuating handle 11 a cap 34 which is larger in diameter and rounded at the front end and which is connected to the actuating plunger 32 via a detachable threaded connection 38.
  • At least two oppositely arranged cams 26 protrude into the axial displacement area of the rounded cap 34, each of which is arranged on the inside at a front end of an associated leaf spring 28.
  • Each of the leaf springs 28 arranged opposite on the holding rod 12 is connected at its other end 35 to the holding rod 12.
  • The, for example, hemispherical cams 26 protrude unactuated into a transverse bore 24 of the support rod 12.
  • the holding rod 12 consists of two parts which can be joined together, a front rod attachment 25 receiving the leaf springs 28 being releasably connected to the rear part of the holding rod 12 via a thread 31 arranged in a bore 36.
  • the rod attachment 25 and the front end of the support rod 12 are designed such that the outer contours of the leaf springs 28 and the rod attachment 25 form the same outer diameter as the support rod 12.
  • Each of the preferably four arranged leaf springs 28 lies in a recess 30 of the rod attachment 25, to which they are connected at the rear end 35 of the recess 30. Because the rod attachment 25 is additionally formed ogival at its front end, a gentle insertion of the holding rod 12 with respect to the propellant charge modules 17 is thus made possible.
  • a compression spring 40 is provided, which is arranged around the actuating plunger 32 and between an axially extending outer bore 42 of the handle 10 or the holding rod 12 and an opposite bore 44 of the actuating handle 11 and can be supported on the end faces of the bores 42, 44 .
